(immune-MACHINE.

To all whom 'it may concern:

Be it. known that we, HARRY E. DiLL and W JLLIAM l). MARSH, citizens of the United States, residing yat Dayton, in the county of Montgomery and State of Ohio, have i11- vented cert-ain new andi useful Improvements in Crimping-ltlachines, of which the following is a specification.

Our invention relates to paper working mechanism, and particularly to a crimping machine for folding inward upon itself, the edge of a tubular body.

'lhe machine forming the subject matter hereof is especially adapted for securing the bottom in paper bottles in the manner shown and described in U. S. Patent No. 667,218, issued February 5 1901 to John H. Hanks.

The object of the invention is to produce a machine for performing the operation described in the aforementioned patent, which will not only be cheap in construction, but will be reliable and -eiicient in operation, capable of being rapidly operated by unskilled labor, whereby the paper bottle forming the subject matter of the above mentioned patent and similar structures may be `produced at minimum cost, and which will be unlikely to get out of repair.

Further objects are to provide improved means for turning the fold at the bottom of the bottle inward over the flange of the bottom section automatically, and to provide eflicient means for securely holding the bottle during such operation.

With the above primary and other incidental objects in view as will more fully appear from the specification, the invention consists of the means, mechanism, construction, and mode of operation, or their equivalents, hereinafter described and set forth in the claims. y

Figs. 10 and 11 are sectional views of the lower portion ofthe paper bottle, before and after the crimping or folding operation re-A spectively.

Like parts are indicated by similar characters of reference throughout the several views.

In constructing the machine there is employed a bed portion l which may be supported on suitable legs, or secured on a bench or table. Located on the bed 1 and adjacent to one end thereof is a head 2 having uprights 3 in which are formed bearings 4 for a longitudinally movable, revoluble shaft 5. Located on the shaft 5 between the uprights 3 is a drive'pulley 6, provided with a feather or key 7 engaging the key way 8 in said shaft 5, whereby said shaft may be shifted longitudinally through said pulley and bearings, While being at the same time rapidly revolved through the medium of said pulley. The shaft 5 is reciprocated by a lever 9 pivoted to a link 10, which in turn is pivoted to a lug 11 projecting from one of the uprights 3. The operating lever 9 is provided with studs 12 which engage a bearing collar 13 located in a groove 14; in a collar 15 secured to the shaft 5.

Secured on the bed 1 in axial alinement with the shaft 5 is the gripper or holder for the work, which comprises a hollow conical body 16 divided longitudinally into an upper and a lower portion. The holder is of such diameter and angle or inclination as to conform to the shape of the bottle or other article to be operated upon. The main portion of the holder is supported upon standards 17 and a base 18 resting on the bed 1. The bed 1 is preferably formed with a central slot 19 within which the head 2 and the holder are engaged in a usual manner by clamp screws or otherwise, in order that the holder for the work and the head 2 by which the crimper or folder is carried may be ad.- justed to and from each other.

Each of the halves of the holder are provided with overlapping lugs 20 .through which extends a pin 21 thereby hinging the two halves of the holder together. One of 'the lugs of the lower half extends into the plane of movement of the corresponding lug of the upper half as at 22, the lug of the upper half being extended as at 23 to engage said projecting lower lug, whereby the relative movement of the parts about their hinged connection will be limited, as shown by dotted lines in Fig. 6. On the side opposite the hinge lugs each halfof the holder is provided with lugs 24 registering wlth eheh other and further provided w1th dowel pins to insure the proper registry of the respective halves of the holder. rI he upper half of the holder is further provided with a lug 25 to which is ivoted a lever 26, recessed at its lower en at 27 to engage a lug 28 project-ing from the lower half of the holder. The upper end of the lever 26 1s curved outward and carries a handle 29, by which the lever may be disengaged from the lug 28, and the upper half of the holder turned 011 its hinge connection as shown by dotted lines in Fig. 6. The lower end of the lever 26 is beveled at 30 to enable it to more readily engage the lug 28. The curvature of the upper art of the lever and the weight of the han( le tends to turn the lever on its pivotal connection, whereby the hooked extremity of the lever will automatieally engage the lug 28 when the holder is closed.

It has been found in practice that stock of different grades requires slightly different treatment, further stock of a given grade will vary in its characteristics under varying atmospheric conditions. To provide for this two interchangeable folders or crimper heads are employed. The heads only differ in that one is provided with a lurality of rollers. Referring first to Figs. 4, 7, 8 and 9, the folder head comprises a circular portion 31 having a shank 32 adapted to engage in a socket in the end of the shaft 5. The forward peripheral edge of the head is rabbeted at 33, the central portion being slightly conical or inclined at 34 to correspond with the inclination of the sides of the bottle or other article operated upon. The angle of t-he peripheral rabbet is recessed at 35a semieircular groove being formed therein, the Vsaid groove projecting inward toward the axis of the head below the surface of the projecting conical portion 34, forming a shoulder 36, which-while well defined is by no means abrupt. The opposite side of the groove 35 is inclined outward, orl formed flaring as at 37. The head show'n in Fig. 3

' is shaped as already described, and is further recessed at regular intervals, in which recesses are located bearing blocks 38 secured in place by screws 39. J ournaled in the bearing blocks. 39 are rollers 40 each vhaving therein a groove 41 whereby the roller will conform to the shape of the rab- `bet 33 and recess or groove 35. Whereas the head of Fig. 5 presses upon the Work and operates by friction only, the head of Fim 3 possesses in addition a rolling action.

he articles to be operated upon are presented to the machine in ,the condition shown in Fig. 10, with the bottom ft2 scoured therein, and the sides 43 projecting beyond the fiange 44 of the bottom 42. The work to be performed consists in folding` the projecting edge of the sides inward and back upon the flange 44, as in Fig. 1l. ln as muchas the diameter of' the bottle at the lower edge in Fig. 1() is greater' than the diameter of the interior 4of the bottle in a plane adjacent tothe bottom section, due to the inclination of the sides of the vessel, the inturned portion of the sides must be reduced somewhat in circumference, which is accomplished by forming therein numerous minute crimps or plaits. By the action ot the crimper head the inturned portion of." the vessel sides is folded and pressed to parallelism. The forward portion of the holder 16 is reduced to a comparative sharp edge, to permit the crimper head to closely approach the holder without interference. However the holder 16 has no part whatever in the folding or crimping operation, further than a support for the article, and to prevent it rotating with the crimper head. As shown in Fig. 8 the forward portion 34 of the crimper head projects within the holder 16 atthe limit of its movement, and presses outward the inturned edge against the interior of the holder. The depression back of the shoulder 36 relieves the pressure on the bended edge of the paper'and prevents cutting` of same. The Haring o'uter periphery of the depression first engages the paper and guides the edge into the groove by which it is reversed upon itself, the longitudinal movement pressing the reversed edge inward to the limit of its movement to form the overlapped edge.

From the above description it will be apparent that there is thus produced a machine of the character described, which possesses the particular features of advantage before enumerated as desirable, but which y obviously is susceptible of modification in its form, proportion, detail construction, and arrangement of parts, without departing from the principle involved or sacrificing any of its advantages.
